WEATHER-STRIP.

Specification of Letters Patent. Patented lilay 31, 1921,

Application filed September 27, 1917. Serial No. 193,521.

To aZZ whom it may concern:

Be it known that I JOSEPH P. GLASER, citizen of the United States, residing at 109 Third AveQDetroit; in the county of lVayne and State of Michigan,'hav e invented certain new and usefullmprovements in eather-Strips, of which the following is a specification, reference being had therein to the 'accompanying drawing.

The present invention relates to improvements in weather strips and more especially has to do with that type of devices particularly adapted for casement windows and the like, in which a metal strip element applied to the sill of the window frame is employed to cooperate with a part or metal strip element on' the lower rail of the sash.

The primary object of the invention is to provide an improved sill strip capable of being readily adjusted to suit sill and sash rail structures of different widths, to provide an improved adjustable sill strip of this nature that will be simple in construction, strong and durable. and that can be manufactured very cheaply.

The invention, with other objects and advantages thereof and the particular construction, combination and arrangement of parts comprising the same will be understood from the following detailed description considered in connection with the accompanying drawings forming part hereof and wherein is illustrated a preferred em bodiment of the invention and one modification thereof.

In the drawings:

Figure 1 is a vertical section of a casement window equipped with a weather strip constructed in accordance with the present invention, the sash being shown in closed position.

Fig. 2 is a detailed perspective view of the sill strip.

The invention comprehends a sill strip made up of two metal members, each of the members having an upstanding part for cooperation with a part on the sash, and with an outstanding portion, said members adjustably interfitting together with the upstanding parts separated from each other and the outstanding portions overlapping each other and forming a channel therebetween.

The particular embodiment of the invention illustrated in Figs. 1 and 2 of the upstanding 'wallsof the flange 6, below drawings comprises a sill strip composed of two members AB formed from strips of flexible sheet metal, such as sheet zinc, copper and the like. The member A has two flanges a-a at opposite sides thereof with an intermediate outstanding connecting portion at, said member being formed by turning up opposite side marginal portions of the strip. In forming the member B, the strip of metal is doubled back upon itself intermediate its side marginal portions to provide a double wall upstanding flange Z), and the outstanding portions Z) b at opposite sides of the flange b, the latter flange b at its upper portion being bent at an angle to provide the offset portion 6 the opposite the portion 6, being separated to provide a spaceb therebetween. The-members AB are assembled in interfltting relation, as shown in Fig. l of the drawings, with the outstanding flz'inge or portion 6 of the member B fitting over the outstanding flange a ofthe member A, and with the upstanding flange a of the member A extending upwardly within the space 5 between the opposite walls of the flange Z), the space 6 being of suflicient width to permit the lateral shifting of the flange a within the said space in the lateral adjustment of the members A-B relative to each other to vary the distance between the upstanding flanges ab of the respective members. The interfitting members are se- I. for cooperation with the sill strip is a 1 metal strip element K, said strip elementK having at one side thereof a substantially hook-shaped resilient pocket 7:.

When the window sash is in its closed position, that shown in Fig. 1 of the drawings, the outwardly bent upper portion 6 of the flange b fits tightly within the resilient pocket '70 of the sash strip K, and the upstanding flange aof the member A of the strip abuts tightly against a part on the lower portion of the sashrail I. In this special instance, the .sash rail is provided with a rabbet Z in which the upper end of the flange a fits with its inner face tight against the inner wall Z of the rabbet.

In order to permit the escape of any moisture that may enter the channel between the upstanding flanges (L -J), small openings (Z are provided in the lower portion of the flange a.

It will be noted that the invention provides for a very eflicient weather proof fitting, the sill strip is of a strong, durable nature, simple in construction, and can be economically manufactured from stock ma terials. The adjustable feature of the sill strip is of practical importance facilitating installation and making it possible to employ one size of strip to equip sill and sash parts of different widths.

I desire it to be understood that minor changes and variations in the particular construction as illustrated in the drawings as will appeal to those skilled in the art and within the scope of the appended claims may be made without departing from the spirit of the invention.

What I claim is:

1. A sill strip for casement windows and the like comprising a metal member having two spaced upwardly extending flanges and an intermediate connecting portion, and an associated member adjustably interfitting with the other member formed of an independent strip of metal folded upon itself to provide a double walled upstanding flange and a horizontally extending base flange at one side thereof, the opposite walls of the double walled flange being separated from each other to provide a space therebetween, one of the upwardly extending flanges of the other member being disposed within and adapted to be positioned at different points within said space in the adjustment of the members relatively to each other.

2. A sill strip for'casement windows and the like, comprising a metal member having two spaced upwardly extending flanges, and an intermediate connecting portion, and an associated member adjustably interfitting with the other member and formed of an independent strip of metal folded upon itself to provide a double wall upstanding flange, the upper portion of the flange being bent outwardly at an angle, and the opposite side walls of the flange below said outwardly bent upper portion being separated from each other to provide a space thereb'etween to receive one of the flanges of the other member and permit of the positioning of the same at different points within said space, one of the flanges of the upper member being disposed within said space between the walls of the flanges of the other member.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

JOSEPH P. GLASER.
